Description
BACKGROUND
[0001] A Radio Frequency Identification (RFID) tag is a type of
electronic identification device that may be used to identify and
track various objects. In practice, an RFID tag is attached to an
object, and an RFID reader senses the presence and identifying
information associated with the RFID tag. The RFID reader may be
located at an entrance or exit of an environment, thus facilitating
the tracking and identifying of objects having RFID tags that enter
or exit the environment.
[0002] RFID tags may be added to existing objects so that they may
be tracked. To this end, an RFID tag may be mounted to the exterior
of an object using adhesives or shrink wrap. However, by being
mounted to the exterior of an object, the RFID tag may impede the
intended functionality of the object. For example, if an RFID tag
were mounted to the exterior of a hand tool, such as a screwdriver
or nut driver, the hand tool may not be able to fit into tight
spaces due to the increased size of the tool.
[0003] Additionally, hand tools may be used in industrial or
mechanical environments, such as in a mechanic shop. As such, the
hand tools are often dropped and may be exposed to other types of
impacts during use. With an RFID tag mounted to the exterior of a
hand tool, the RFID tag may bear the brunt of such impact, thereby
increasing the likelihood of failure of the RFID tag.
[0004] Even further, hand tools are often used in environments
where corrosive chemicals are present. If an RFID tag were mounted
to the exterior of a hand tool, these chemicals are likely to make
contact with the RFID tag and possibly cause failure of the RFID
tag. Accordingly, there exists a need for an RFID-enabled hand tool
that is protected from chemical exposure, able to withstand
mechanical impact, and limits interference with the intended
functionality of the hand tool.

DETAILED DESCRIPTION
[0009] The present disclosure is direct towards a hand tool having
an electronic identification device. As a non-limiting example, a
handle of the hand tool includes a cavity configured to receive a
plug. The plug at least partially encapsulates an RFID tag and is
inserted into the cavity of the handle. The plug may provide a seal
with respect to the cavity, thereby protecting the RFID tag from
being exposed to corrosive chemicals. Additionally, by the RFID tag
being in the interior of the plug and the handle, the RFID tag may
be shielded or cushioned from impacts. Even further, by being
placed in the interior of the handle, the RFID tag may not
interfere with the intended functionality of the hand tool. In the
following discussion, a general description of the system and its
components is provided, followed by a discussion of the operation
of the same.
[0010] With reference to FIGS. 1A-1C, shown is a hand tool 100
according to various embodiments of the present disclosure. The
hand tool 100 includes a handle 103, a shaft 106, a plug 109, an
electronic identification device 113, a cap 115, and possibly other
features not discussed in detail herein. The hand tool 100 shown is
embodied in the form of a nutdriver. However, it is emphasized that
in various embodiments, the hand tool 100 may be embodied in the
form of, for example but not limited to, a screwdriver, a bit
driver, a hammer, a mallet, a wrench, a cutting tool (e.g.,
scissors, a knife, etc.), a file, a scraper, a spatula, a chisel, a
chisel holder, an awl, a punch, a brush, a broom, an axe, a pry
bar, an extension mirror, an extension magnet, a level, or any
other type of hand tool 100.
[0011] The handle 103 is a portion of the hand tool 100 that is
configured to be gripped by a user, as may be appreciated. For
example, in the case in which the hand tool 100 is a nutdriver, the
handle 103 is the portion of the nutdriver that a user grips and
rotates in order to tighten or loosen a fastener (not shown). The
handle 103 may also include multiple grooves 116 or other features
to facilitate a grip by a user. It is noted that the handle 103 may
comprise a material that is transparent or semi-transparent to
radio frequency energy, in order to facilitate the transmission of
signals to or from the electronic identification device 113.
[0012] The handle 103 also includes a cavity 105. The cavity 105
may be configured to receive and at least partially encapsulate the
plug 109. The cavity 105 may be formed in the handle 103 during
manufacture of the handle 103, or a cavity 105 may be fabricated in
a preexisting handle 103. The cavity 105 may be formed in a
preexisting handle 103, for example, by drilling into the
preexisting handle 103.
[0013] The shaft 106 is attached to and extends from the handle
103. To this end, a portion of the shaft 106 may be disposed in the
handle 103. To secure the shaft 106 to the handle, and to prevent
rotation of the shaft 106 with respect to the handle 103, the
portion of the shaft 106 that is disposed in the handle 103 may
include multiple outwardly extending fins 119.
[0014] At the opposite end of the shaft 106 may be a driver 123.
The driver 123 may be configured to receive and rotate fasteners
(such as but not limited to, screws, bolts, nuts, etc.), bits (e.g.
Phillips bits, flathead bits, hex-head bits), or other items.
[0015] The electronic identification device 113 emits an
identifying signal that is capable of being received by an
appropriate reader (not shown). The identifying signal may include
data that uniquely corresponds to the electronic identification
device 113, thereby facilitating the identification of the hand
tool 100 to which the electronic identification device 113 is
attached. The electronic identification device 113 may be active,
semi-active, or passive and may or may not include storage memory.
In various embodiments, the electronic identification device 113
may be embodied in the form of an RFID tag or another type of
electronic identification device 113 capable of emitting an
identifying signal.
[0016] The plug 109 is configured to at least partially encapsulate
the electronic identification device 113 and be inserted into the
cavity 105 of the handle 103. In order to facilitate transmission
of signals to and from the electronic identification device 113,
the plug 109 may comprise a material that is transparent or
semi-transparent to radio frequency energy. Additionally, the plug
109 may comprise a compressible material so as to facilitate a snug
fit in the cavity 105. As such, the plug 109 may comprise an
elastomeric material, for example.
[0017] Turning to FIGS. 2A-2D, shown is one embodiment, among
others, of the plug 109. In the embodiment shown, the plug 109 is
substantially cylindrical, but it is emphasized that other shapes
of plugs 109 may be used as well. The plug 109 includes a first end
206, a second end 209, an exterior surface 213, a receptacle 216,
and other features.
[0018] With the plug 109 inserted into the cavity 105 (FIGS.
1A-1C), the first end 206 may face away from the shaft 106, and the
second end 209 may face towards the shaft 106 (FIGS. 1A-1C). The
exterior surface 213 of the plug 109 extends between first end 206
and the second end 209. In various embodiments, the plug 109 may be
tapered to facilitate insertion into and retention within the
cavity 105. In this sense, the exterior surface 213 may taper
(e.g., reduce in diameter) as it extends from the first end 206 to
the second end 209.
[0019] The receptacle 216 receives and retains the electronic
identification device 113 (FIGS. 1A-1C). To this end, the
receptacle 216 may include an opening 219, an interior wall 223,
one or more lips 226a-226b, one or more ports 229a-229b, and
possibly other features. With the electronic identification device
113 inserted into the receptacle 216, an interior-facing side (not
shown) of the electronic identification device 113 may abut the
interior wall 223. Similarly, a portion of the exterior-facing side
(not shown) of the electronic identification device 133 may abut
the one or more lips 226a-226b. Thus, the lips 226a-226b may retain
the electronic identification device 113 within the receptacle 216
and thus the plug 109.
[0020] The ports 229a-229b correspond to and may facilitate
construction of the lips 226a-226b. For example, in the event that
the plug 109 is manufactured using an injection molding process,
the material from which the plug 109 is formed may be injected
around into a mold (not shown). Upon the material setting, one
portion of the mold may form the lips 226a-226b and be removed
through the ports 229a-229b, while another portion of the mold may
form the interior wall 223 and be removed through the opening
219.
[0021] The plug 109 may also include one or more seals 233a-233d to
prevent fluids or debris from entering the cavity 105 and/or the
receptacle 216. The seal 233a is disposed around the exterior
surface 213 near the first end 206 of the plug 109. The seal 233a
may be formed as part of the plug 109, or the seal 233a may be
embodied as an O-ring, for example. Upon the seal 233a being flush
with the cavity 105, the seal 233a may prevent fluids or debris
from entering the cavity 105 and thus the receptacle 216.
[0022] The seal 233b at least partially surrounds the opening 219
of the receptacle 216, and the seals 233c-233d at least partially
surround the ports 229a-229b. With the plug 109 inserted into the
cavity 105, the seals 233b-233d may become flush with the cavity
105 and thus prevent fluids or debris from entering the receptacle
216.
[0023] The plug 109 may further include one or more protrusions 236
that may be disposed towards the second end 209 of the plug 109 or
on other areas of the exterior surface 213. The protrusions 236 may
be configured to abut against the cavity 105 upon insertion. As
such, the protrusions 236 may prevent the second end 209 from
moving with respect to the cavity 105. Additionally, the
protrusions 236 may provide cushioning for the electronic
identification device 113 upon the hand tool 100 (FIGS. 1A-1C)
being subjected to an impact.
[0024] Turning now to FIGS. 3A-3B, shown are caps 115, referred to
herein as caps 115a-115b, according to various embodiments. The
caps 115a-115b may be attached to the handle 103 (FIGS. 1A-1C)
and/or the first end 206 (FIGS. 2A-2D) of the plug 109. By being
constructed separately from the plug 109, several different caps
115a-115b may be manufactured to fit a single style of the plug
109. Accordingly, manufacturing costs may be reduced.
[0025] The caps 115a-115b may include indicators 303a-303b,
respectively, that indicate the type of hand tool 100 (FIGS. 1A-1C)
to which a cap 115a-115b is attached. In various embodiments, the
indicators 303a-303b may be embodied in the form of apertures. In
this sense, the 303a-303b are "cut-outs" from the caps 115a-115b.
As non-limiting examples, the indicator 303a is an aperture that is
in the shape of a hexagon, while the indicator 303b is an aperture
that is in the shape of a square. In this example, the cap 115a may
be attached to a hand tool 100 having a driver 123 (FIGS. 1A-1C)
that fits a hex-head bolt, while the cap 115b may be attached to a
hand tool 100 having a driver 123 that fits a square-head bolt.
[0026] Additionally, the plug 109 may have a color that differs
from the color of the cap 115. Thus, with the hand tool 100
assembled, the color of the plug 109 may be visible through the
indicator 303a-303b aperture of the cap 115a-115b. As a
non-limiting example, if a red plug 109 and a black cap 115a having
a hexagon indicator 303a were used, a red hexagon would be visible
through the black cap 115a.
[0027] Next, a general description of the operation of the various
components of the hand tool 100 is provided. To begin, it is
assumed that the components have been assembled and that the shaft
106 is attached to the handle 103. As described above, the handle
103 may be manufactured so as to include the cavity 105. Otherwise,
if a preexisting handle 103 lacks the cavity 105, the handle 103
may be retrofitted with the cavity 105, for example, by using a
drill.
[0028] The electronic identification device 113 may be inserted
into the receptacle 216 of the plug 109 so that the electronic
identification device 113 is at least partially encapsulated within
the plug 109. With the electronic identification device 113 being
inserted into the receptacle 216, the lips 226a-226b may abut an
outward facing side (not shown) of the electronic identification
device 113. Thus, the lips 226a-226b may facilitate retaining the
electronic identification device 113 within the plug 109.
[0029] With the electronic identification device 113 at least
partially encapsulated within the plug 109, the plug 109 and the
electronic identification device 113 may be inserted into the
cavity 105 of the handle 103. The seals 233a-233d may then become
flush against the cavity 105, thereby preventing fluids and debris
from making contact with the electronic identification device 113.
Additionally, a sealant or adhesive may be applied to the cavity
105 and/or plug 109 to prevent penetration by fluids and debris and
to further retain the plug 109 within the cavity 105. Thereafter,
the cap 115 may be applied to the first end 206 of the plug 109
and/or the handle 103 by using an adhesive, mechanical attachment
(e.g., threads), or other methods.
[0030] It is emphasized that the above-described embodiments of the
present disclosure are merely possible examples of implementations
set forth for a clear understanding of the principles of the
disclosure. Many variations and modifications may be made to the
above-described embodiments without departing substantially from
the spirit and principles of the disclosure. All such modifications
and variations are intended to be included herein within the scope
of this disclosure and protected by the following claims.
